Notes to the characteristics
1. All characteristics are measured using the circuit shown in Fig.4.
2. The circuit is DC adjusted at V
P
= 6 V to 18 V and AC operating at V
P
= 8,5 V to 18 V.
3. At 18 V < V
P
< 30 V the DC output voltage ≤ V
P
/2.
4. Output power is measured directly at the output pins of the IC.
5. Frequency response externally fixed.
6. Ripple rejection measured at the output with a source impedance of 0 Ω (maximum ripple amplitude of 2 V) and a
frequency between 100 Hz and 10 kHz.
7. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
8. Noise output voltage independent of R
S
(V
I
= 0 V).
